The Bolthold AK-4 kit provides you with the correct amount of anchors and grout for securing anchors into asphalt. The included SP10-38 anchors are ideal for anchoring bike racks, signs, machinery, and more into asphalt surfaces. The SP10-38 asphalt anchor requires a 7/8" hole that is 6" deep. The length of the bolt inside the anchor should not exceed 3". Each anchor is pre-installed with a 1" long hex bolt and a 1" diameter washer.

You can load the anchors at 80% of their pull rating if the object/structure stands solidly by itself. If the object applies a static pull force on the anchors just as it stands, limit the load to 20% of the pull rating.

Asphalt Anchor Features:

  • Asphalt Anchors are mounted flush with the surface.
  • A 1.4" header at the top of the anchor prevents the anchor from dropping below the surface and being pulled up into the mounting plate once the bolt is tightened.
  • The attached objects can be easily removed without leaving protrusions on the surface.

Kit Includes:

For step-by-step instructions on how to properly install asphalt anchors with grout, see product guide document listed in the specifications tab.

Just installed so I cannot say anything about longevity but the kit is very user friendly.
